Marc Zyngier 7828a3ef86 irqchip: Fix probing deferal when using IRQCHIP_PLATFORM_DRIVER helpers
When probing an interrupt controller that is behind a parent,
we try to check whether the parent domain is available as
an indication that we can actually try to probe.

Unfortunately, we are checking this with the firmware node of
the about to be probed device, not the parent. This is obviously
bound to fail.

Instead, use the parent node.

Fixes: f8410e6265 ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
